Cruise Line postcards ideas?

Every now and then I get these really great postcards from the Disney Cruise line offering me special AP FL resident rates (great rates BTW.) Anyway, the postcards are those ones that the picture changes when you tilt the card (don't know what they are called) so I keep them because they are adorable. But I've not gone on a cruise. Any idea about how I might make use of them? Maybe a 'someday' page or something?
I got one yesterday that has Lilo and Stitch in a hammock and I have another one with Mickey, Goofy and Donald on it. Oh, and to make it trickier they are big, 5 1/2 by 8 1/2.

I just got this too!! My husband didn't even see it before it was off with my scrapbooking stuff.

I was thinking about using it on two page spread that was "Ohana" ie family. Would probably use it like it was a photo too. Maybe next time you find yourself around a hamock make a similar pose and put photos side by side. Anyway.......
